Specification of Letters Patent.

To all ich-0m 2f-may concern.' i

Be it knownV that I, FAYETTE G. Nnwron, a citizen of the United States, and a resident of West Springfield, in the county of Hampden, State of Massachusetts, have in- 'vented certain new and useful AImprovements in Electric Switches, of which the following is a specilication.

The invention relates particularly to an electric switch of the push button type, for instance such as lshown in the patent to Monroe Guett, No.'972,365, dated Oct.,11, 1910; and the object of the invention is to improve the construction of switches of this character, and particularly to provide a mechanism whereby two or more circuits can be controlled by controlling the movements of the switch plates.

Referring-to the drawings: Figure 1 is a side view of a switch embodying my invention some parts being removed to more clearly show the structure. Fig. 2 is an end View of a part of the switch illustrating my invention. Figa?) is a transverse section view of the interior of the receptacleadapted for use with my switch. Fig. 4 is a side elevationot` a switch embodying my invention .in its intermediate position. Fig. 5 is a diagrammatical view of the switch showing the circuits when the parts are in inactive position. Fig. 6 is a similar view when the parts are in intermediate position. Fig. 7 is a similar view showing the parts in the other extreme position.

Referring to the drawings 1 2 denote the push buttons, 3, 3 the switch plates, 4 the oscillating plate with which the push buttons are connected,v 5-6 two locking anges on this oscillating plate, 7 a locking member pivoted on the frame having radial arms 8 9, one of which, 8, hasiloclting projections 10-11, adapted to cooperate with the flanges 5 6 resepectively, on the oscillating plate 4, the other arm 9 carrying a pin 12, which is in engagement with a part secured to the poles. TheI usual snap mechanism including a spring indicated at 13 is interposed between the oscillating plate 4 and the switch plates 3. A

In the operation of this device it will be seen that ift the push button 1 is pressed down, lthe oscillating plate 4, connected with it, will be turned on the s indle, moving the flange 5 under the loc ing projec-.

tion 11, and at the same time-one end of the actuating spring 13 is moved by an arm on the oscillating plate. The poles arev held against movement because they are engaged by the pin 12 mounted on the arm 9 of the locking member 7, and as the other end of the spring is held by another arm fixed to the poles, the movement of the oscillating plate l vwinds up or makes tense the spring 13. AWhen the flange 5 passes from under the locking member 7 is the projection 11,

the poles and permitting released, releasing the spring 13 to move the poles.

Since the poles are released when the oscillating memsioning the spring untilthe flange 6 passes from under the projection 10, when the spring throws the switch platesto their eX- treme position. Oi course, as the push button 1 is being depressed, the push button 2 is being released. It now, the push button 2 is depressed, tlie operation is repeated, but in a reverse direction. The under part of the flange 6 now travels over the upper end of the locking projection 10 until the vswitch plate moves to its intermediate position, and then the under part of the flange 5 rides over the upper end of the locking projection 11 until the switch plates are again released.

In one extreme position of the switch plates, indicated diagrammatically in Fig. 5, which may be termed the inactive position, it will be notedthat the switch plaies 3, 3 are out of engagement with the cor.- tacts 15-16 and`17f-18, and the two lights L, L are out. In the intermediate position illustrated diagrammatically in Fig. (3 the switchplate 3. is still outof engagement with contacts 17-18 while the switch plate 3 is in contact with the upper ends ot' the contacts 15-16 and the light L" is lighted. Iii the other extreme position illustrated di- Iconnection with electroliers providedv with two separate sets of lights so that the circuits of both sets of lights can be separately controlled.

I claim:

l. In anelectric switch a pair of switch plates adapted for movement in either direction between two extreme positions, and

means for stopping said switch plates at any intermediate point, in combination with a set of circuit-terminals adapted to be engaged by one only of said switch plates when in their intermediate position, and a second set of circuit terminals adapted to be engaged by the other switchv plate in one of its extreme positions.

2. The combination with a receptacle having sets of terminals for separate electric circuits, of a switch mechanism located in said receptacle comprising an :oscillating switch plate for cach circuit, operating mechanism for said switch plates and a reciprocating handle to actuate said operating mechanism, of terminals being ldisplaced relatively to one anotlier'inthe direction. of movement of the switch plates, whereby said circuits may be closed and opened separately.

3. In an electric switch the combination vwith a plurality of oscillatory switch plates, a plurality of stops connected with said switch plates, Ya plurality of locking members connected with said ppcratiiig member, and adapted to coperate with the .plurality of stops successively, of 4a receptacle in which said switch is mounted and a plurality of setsof terminals for separate circuits inA said receptacle.

4. In an electric switch the combination with a receptacle having sets of terminals vfor separate circuits, of a switch mechanism located in said receptacle, an Aoscillating plate for each set of terminals, an 'operating handle, means for holding said switch plates i against movement during the initial movement of said-operating handle, means actuated by said handle for releasing said holding means, and means for stopping the -movement of said switch plates at a point intermediate of the extreme positions of said switch plates.

5. In an electric'switch of the push button i type adapted for the controlling of separate circuits, a pair of oscillating switch plates, an operating member, a springv interposed between and connecting said switch plates and operating member, push buttons connected with said operating member, av controlling member connected with said switch plates, and aseries of stops on said operating member adapted to be engaged successively by said controlling member, whereby said plates may be stopped at a poi'ntintermediate of their two extreme positions when moving in'v either direction.

G. Ina switch of the character described,

a paiit'of switch vplat-es, an operating member, a springinterposed between and connecting said switch plates and operatin member, push buttons connected with sai operating member, a pair of locking-anges on said. operating member, 'aJ controlling member connected with saidA switchy plates, and a pair of locking projections on said controlling member adapted to coperate with said locking flanges 'for the purposes specified.
